Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U25,000 per hour. In this case the liners sections are t each. For smaller mills the liners have to be handled and installed manually, so smaller blocks with

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

Understanding Mine to Mill is presented in five parts. Part A Setting the Scene provides some definitions of Mine to Mill (M2M) and the historical background. A chronology of Mine to Mill developments is followed by brief descriptions of the very wide range of Mine to Mill applications which have been implemented over the last 15 years.

Semiautogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diametertolength ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

Outotec has recently been awarded a contract to deliver one of the largest grinding mills in the world. The contract includes the design and manufacture of a Ø 40' x 29' SAG mill. The mill will be driven by a Gearless Motor Drive (GMD) which at MW is equal to the largest grinding mill power ever used in the mining industry.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills.

SAG Mill Components. Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of ...

We have an application in a SAG Mill where we have installed an electronic ear in order to listen the noise produced by the balls falling to the bottom of the mill. Our idea is to convert the amplitude and frequency of noise to a 420mA signal (or something else) in order to determine if the ball is crushing the mineral or the mill lining.

A broken liner, which is particularly severe for large AG/SAG mills, can arise from media impacting directly on the mill liner. Multotec's rubber mill linings are designed by combining the results of computer simulations and inspection data in order to optimise charge trajectory and wear life.
